Characteristics of a buoyant plume in a channel with cross-flow [PDF]

open access: yesInternational Journal of Heat and Fluid Flow, 2020
Motivated by tunnel fires, wherein the smoke is purged out of the tunnel by a ventilating crossflow, we undertake a fundamental study of buoyant plume with crossflow in channel using direct numerical simulation. The plume originates from a spanwise extended line heat source at the bottom channel wall, and after rising and impinging the top wall, the ...
